I understand Government was unhappy with management of Sydney Harbour.  Sydney Harbour and part of Botany Bay have been taken from council control and are administered directly by NSW Government or by a government authority of which I am not aware. There may be other areas as well but I have no other information.

The website was formerly lpi.nsw.gov.au and became spatial.nsw.gov.au but I think we still have permission for the specified datasets as noted in the OSM contributors pagehttps://wiki.openstreetmap.org/wiki/Contributors#New_South_Wales_Government_data

The DCS Base Map, accessible through at least some OSM editors, shows at least some of the LGAs boundaries.
It does not show the 'unincorporated areas' at all, at least not with my eyes.

It includes "Unincorporated - Sydney Harbour Area" and "Unincorporated - Botany Bay Area".  The Sydney Harbour Area includes much of Parramatta and Lane Cove Rivers as well as various bays such as Homebush Bay and Canada Bay. OSM currently shows the limits of LGAs administered by councils but does not show the Unincorporated Sydney Harbour area.

That link is at least useful even though OSM cannot use it.

The present OSM data shows, for example, the Australian Nation Maritime Museum as an unincorporated area where the above link shows it as administered by the City of Sydney LGA.
